Russia Wants a Hypersonic Bomber 319
derekmead writes "Hot on the heels of the U.S. Air Force's most recent failed test of an unmanned hypersonic vehicle, Russia now says it wants to jump into the hypersonic game with a long-range bomber. Will Russia's newest Bear fly at 4,500 miles an hour? The Russian military sure hopes so. 'I think we need to go down the route of hypersonic technology and we are moving in that direction and are not falling behind the Americans,' Russian Deputy Prime Minister Dmitry Rogozin said on Russian television. 'The question is will we copy the Americans' 40-year experience and create a [Northrop] B-2 analog or will we go down a new, ultramodern technology route, looking to the horizon, and create a machine able to penetrate air defenses and carry out a strike on any aggressor.' The Russians want their plane operational by 2020, which doesn't seem particularly realistic — we are talking about five times the speed of sound here, and Russia is just starting engine development. The U.S., meanwhile, has been investing in its Waverider program since 2004, and the last test of the X-51A scramjet-powered missile failed after just 15 seconds."

Sadly fans don't work in supersonic regimes although if some aerodynamic Einstein ever comes up with a solution then the world will beat a path to her door.
That restricts supersonic flight to rockets, scramjets etc. and to pure jet engines with variable intake nacelle structures that can slow the incoming air to subsonic speeds so it can be compressed, burned and turned into thrust.

Concorde as a plane made a profit. As an aircraft model, it did not. The problem was its huge operating cost for a trans-Atlantic flight (somewhere between $1500-$2500 per passenger - if the crash hadn't killed it, the spike in fuel prices in 2007-2008 would have). That meant your clientele were only a thin sliver of the overall market, and most of them were concentrated on a few routes (between major economic centers, or an economic center and major resort destination). On top of that, a few planes completely saturated your market on a route. That's fine if you're the only carrier which flies the plane on one of those golden routes. But if you were hoping to sell hundreds of the planes to recoup the billions of pounds/francs spent developing the aircraft, you're totally screwed.
Yeah if you got one of the $100 HP Touchpads during its closeout sale, it was hugely profitable for you. But the fact that HP never recouped its huge investment in developing the device means it was a financial failure.

There are other uses to a hypersonic aircraft than simply dodging missiles. The ability to arrive on target in minutes instead of hours, for example. Plus, even if the bomber isn't technically faster than the missile, missiles have limited fuel capacity and require a certain reaction time before they can be fired, so if you can build a bomber fast enough, by the time the missile is fired it can't reach you before it runs out of fuel. This is even more true if you are traveling at extremely high altitudes. If you have a bomber traveling at Mach 5 (1 mile per second, roughly) and a missile traveling at Mach 6 launched at the bomber when it is 20 miles away (easily possible for a high altitude bomber to hit a target that far away), it will take 100 seconds to hit, in which time the missile must travel 120 miles, which is outside the range of, say, a Patriot missile (which travels at Mach 5). And the higher the speed, the more fuel it takes for the same distance. A bomber can afford that. It's a lot harder for a disposable missile to do the same.

After NASA's NASP program was cut, American scientists began to look at adopting available Russian technology as a less expensive alternative to developing hypersonic flight. On November 17, 1992, Russian scientists with some additional French support successfully launched a scramjet engine "Holod" in Kazakhstan6. From 1994 to 1998 NASA worked with the Russian Central Institute of Aviation Motors (CIAM) to test a dual-mode scramjet engine and transfer technology and experience to the West. Four tests took place, reaching Mach numbers of 5.5, 5.35, 5.8, and 6.5. The final test took place aboard a modified SA-5 surface to air missile launched from the Sary Shagan test range in the Republic of Kazakhstan on 12 February 1998. According to CIAM telemetry data, first ignition of the scramjet was unsuccessful, but after 10 seconds the engine was started and the experimental system flew 77s with good performance, up until the planned SA-5 missile self-destruction (according to NASA, no net thrust was achieved).

No, not really. They were softened up nicely in 1941-43, but by the end of 45 were pretty much fully recovered as far as war capacity was concerned. In fact, the USSR was in a better shape by then, because it had all its heavy industry restored and running at full capacity, but this time tucked away safely at Urals, where no German (or American) bomber could have reached. 10 million in casualties sounds pretty bad, and it was, but there were still considerable manpower reserves - we're talking about a count
